Unresponsive Patients Activate a Noninvasive Interface

Name: __________________________ Date: __________________

Read the story

In a study published in Brain on October 22, approximately one third of 41 clinically unresponsive patients controlled an auditory signal through EEG activity.

The technique used scalp electrodes rather than an implant. It remains an initial demonstration, not established two-way communication or evidence of a cure.
